Which standard states that RS485 and power supply cannot share the same cable?

Which standard states that RS485 and power supply cannot share the same cable? Which standard specifies this? Please help.
? If such a standard really exists and it’s said that way, then this standard is also an idiotic standard! Damn idiot, you don’t know it, you haven’t seen it – never mind then. It’s not bad to be a bit pure. :lol

For example, with my probe used for measurements in deep wells, in oil logging applications, do I really need to use two separate cables just for power and communication? Can I use four-core, two-strand shielded twisted pair? Why not use four-core parallel wires? Whether I eat meat or shit, what’s it to you? Who gives a damn about you? If you’re so capable, then go ahead and eat shit yourself. :lol
Come on, if they can write out chemical industry standards, then they should be able to determine whether farts should make 2 sounds or 3 sounds, whether they should be continuous or not, and whether the decibel level should be within limits – farts should be soft farts...... right? .
Hahaha, it was done this way before; it’s just that the design institute required it this time.
Seeing you being so rude – it’s so in my style, which puts me at ease
Same question: some instruments have only one hole for connections. The standards require that the power cable and the signal cable not be placed parallel to each other; what distance must be maintained between them? .
